Item 14. Indemnification of Directors and Officers

The Registrant is governed by the Delaware General Corporation Law, as the same exists or may hereafter be amended (the “General Corporation Law”). Section 145 of the General Corporation Law (“Section 145”) provides that a Delaware corporation may indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative (other than an action by or in the right of such corporation) by reason of the fact that such person is or was a director, officer, employee or agent of such corporation, or is or was serving at the request of such corporation as a director, officer, employee or agent of another corporation or enterprise. The indemnification may include expenses (including attorneys’ fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by such person in connection with such action, suit or proceeding, provided such person acted in good faith and in a manner he or she reasonably believed to be in or not opposed to the corporation’s best interests and, with respect to any criminal action or proceeding, had no reasonable cause to believe that his conduct was unlawful. Section 145 also provides that a Delaware corporation may indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action or suit by or in the right of such corporation, under the same conditions, except that such indemnification is limited to expenses (including attorneys’ fees) actually and reasonably incurred by such person, and except that no indemnification is permitted without judicial approval if such person is adjudged to be liable to such corporation. Where an officer or director of a corporation is successful, on the merits or otherwise, in the defense of any action, suit or proceeding referred to above, or any claim, issue or matter therein, the corporation must indemnify that person against the expenses (including attorneys’ fees) which such officer or director actually and reasonably incurred in connection therewith.

Section 145 further authorizes a corporation to purchase and maintain insurance on behalf of any person who is or was a director, officer, employee or agent of the corporation, or is or was serving at the request of the corporation as a director, officer, employee or agent of another corporation or enterprise, against any liability

asserted against such person and incurred by such person in any such capacity, or arising out of such person’s status as such, whether or not the corporation would otherwise have the power to indemnify such person against such liability under Section 145.

The Registrant’s Amended and Restated Certificate of Incorporation and Amended and Restated Bylaws provide that the Registrant will indemnify to the fullest extent permitted by law any person made or threatened to be made a party to an action or proceeding, whether criminal, civil, administrative or investigative, by reason of the fact that he, his testator or intestate is or was a director, officer or employee of the Registrant or any predecessor of the Registrant, or serves or served at any other corporation, partnership, joint venture, trust or other enterprise as a director, officer, employee or agent at the request of the Registrant or any predecessor of the Registrant.

The Registrant’s Amended and Restated Bylaws provide for mandatory indemnification to the fullest extent permitted by General Corporation Law against all expenses (including attorney’s fees), judgments, fines, ERISA excise taxes or penalties and amounts paid in settlements.

The Registrant’s Amended and Restated Certificate of Incorporation eliminates the liability of a director of the registrant to the fullest extent under applicable law. Pursuant to Section 102(b)(7) of the General Corporation Law, a corporation may eliminate the personal liability of a director to the corporation or its stockholders for monetary damages for breach of fiduciary duty as a director, except for liabilities arising (i) from any breach of the director’s duty of loyalty to the corporation or its stockholders, (ii) from acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law, (iii) under Section 174 of the General Corporation Law, or (iv) from any transaction from which the director derived an improper personal benefit.

The Registrant’s directors and executive officers are covered by insurance maintained by the Registrant against specified liabilities for actions taken in their capacities as such, including liabilities under the Securities Act of 1933, as amended (the “Securities Act”). In addition, the Registrant has entered into contracts with its directors and executive officers providing indemnification of such directors and executive officers by the Registrant to the fullest extent permitted by law, subject to certain limited exceptions.

The proposed form of underwriting agreement to be filed as Exhibit 1.1 to this Registration Statement provides for indemnification by the underwriters of the Registrant and its officers and directors, and by the Registrant of the underwriters, for certain liabilities arising under the Securities Act or otherwise in connection with this offering.

Item 15. Recent Sales of Unregistered Securities

The following is a summary of the Registrant’s transactions within the last three years, involving sales of the Registrant’s securities that were not registered under the Securities Act:

(a)        On January 2, 2014, the Registrant issued and sold an aggregate of 900 shares of common stock to its five founders at a purchase price of $0.10 per share paid in cash. Such shares will undergo a 2,000-for-1 stock split immediately prior to the closing of this offering.

(b)        In March and April 2014, the Registrant issued and sold an aggregate of 201 shares of common stock to 13 persons, including three of its founders, at a purchase price of $10,000 per share paid in cash. Such shares will undergo a 2,000-for-1 stock split immediately prior to the closing of this offering.

II-2

(c)        Between September 2014 and April 20, 2015, the Registrant issued and sold an aggregate of 265.4615 shares of common stock to 37 persons, at a purchase price of $13,000 per share paid in cash. Such shares will undergo a 2,000-for-1 stock split immediately prior to the closing of this offering.

Except as indicated above, none of the foregoing transactions involved any underwriters, underwriting discounts or commissions, or any public offering, and the Registrant believes that each transaction was exempt from the registration requirements of the Securities Act by virtue of Section 4(2) thereof, Regulation D promulgated thereunder or Rule 701 pursuant to compensatory benefit plans and contracts relating to compensation as provided under such Rule 701. The recipients in such transactions represented their intention to acquire the securities for investment only and not with a view to or for sale in connection with any distribution thereof, and appropriate legends were affixed to the share certificates and instruments issued in such transactions. All recipients either received adequate information about the Registrant or had access, through their relationships with the Registrant, to such information.

Item 17. Undertakings

The undersigned Registrant hereby undertakes to provide to the Underwriters at the closing specified in the underwriting agreement certificates in such denominations and registered in such names as required by the Underwriters to permit prompt delivery to each purchaser.

Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers and controlling persons of the Registrant pursuant to the provisions referenced in Item 14 of this Registration Statement or otherwise, the Registrant has been advised that in the opinion of the Securities and Exchange Commission (“SEC”) such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the Registrant of expenses incurred or paid by a director, officer, or controlling person of the Registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered hereunder, the Registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue.

The undersigned Registrant hereby undertakes that:

(1)         For purposes of determining any liability under the Securities Act, the information omitted from the form of prospectus filed as part of this Registration Statement in reliance upon Rule 430A and contained in a form of prospectus filed by the Registrant pursuant to Rule 424(b)(1) or (4) or 497(h) under the Securities Act shall be deemed to be part of this Registration Statement as of the time it was declared effective.

II-7

(2)         For the purpose of determining any liability under the Securities Act, each post-effective amendment that contains a form of prospectus shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

II-8
